SYMPTOMS
If you have Windows NT installed on a partition using the FAT file system,
the boot sector may become corrupted after performing a shutdown.
As soon as the status is returned that each of these functions has been completed, Windows NT displays the following message:
If you immediately turn off your computer, disk corruption may occur that can prevent the computer from restarting. CAUSE
The operating system thinks the file-system shutdown functions have
completed successfully, but there is still an asynchronous thread running
that has not yet completed its I/O to the volume. This process is used to
mark the volume clean by updating information on the disk. If the computer
is powered off while this last write is in progress, disk corruption may
occur. RESOLUTION
If you look closely at the disk access light of a drive running Windows NT
and using the FAT file system, you will see that approximately 7 seconds
after the message is posted stating it is safe to turn off the computer,
further disk activity takes place on the drive.
STATUS
Microsoft has confirmed this to be a problem in Windows NT versions 3.1,
3.5, and 3.51. This problem was corrected in the latest Windows NT 3.51
U.S. Service Pack. For information on obtaining the Service Pack, query on
